I've only given the product a 3 star rating as whilst the internal bifold doors offer a soluton to flexible living space and look OK now fitted, they have been very problematic to fit. The generic instructions were very vague and my experienced joiner found them a nightmare to fit. I don't think the problems are over yet as I think there will be even more issues when I have a new carpet fitted as the trim between the flooring and carpet will need to negotiate the pivot that goes into the floor. I'd read other reviews before buying where people mentioned the vague instructions and just thought people were being negative. But in hindsight I should have taken the warning and looked for a better set of doors. You don't know though until you come to fit them!!!
